Why would it be unknown? The charging system could directly measure its health and confirm its within nominal specs. Plus you only need the new battery to be good for the duration of one trip. There’s always a new one around the corner.
It’s like fretting about the quality of one tank of gas. In the long term it’s meaningless because it’s a fleeting problem and will just remedy itself on the next fill up.
- Kirby64 3y agoBatteries have a given lifespan and number of cycles. If my swapped battery isn't either the same mileage or better, then I'm literally degrading the quality of my car by swapping batteries. I have no guarantees I'd get the same one back on the return trip. This is equivalent to swapping a motor in a gasoline car, not the gas itself. What happens if I swap to a motor that has 100k miles on it on my brand new car? What about one that was poorly maintained (the EV equivalent would be... discharged to low SoC, kept at high SoC often, charged only using DCFC, etc)? You can't detect all of these things or directly measure them, but just like changing the oil too infrequently in a motor they do damage the battery over time. If somehow you could actually always support 'a next battery swap fixes it', then you would have to charge an extremely high cost for such battery swap. There's no way around that.
